Great presentation, you are getting relaxed and comfortable being in front of the camera, it shows, your allowing the information to just flow out and be absorbed by all easily, Great Job!!
Dual shield is actually a trade name for ESAB flux cored gas shielded wires. The process is mistakenly called that at times. FCAW-G or Flux cored arc welding gas (shielded) is the proper name for that process, and it requires gas because the flux contains deoxidizers and elements to give the weld metal different properties based on its application. Self shielded wire is FCAW-S or flux cored arc welding self (shielded). That flux contains elements that create a gaseous shield around the puddle eliminating the need for gas. That wire appears to be a metal cored wire which I believe falls under GMAW or gas metal arc welding commonly referred to as mig. Metal cored wires generally produce little to no slag, They will leave behind some residue on the surface of the weld like was seen on the first weld.
Good explanation uncle crazy legs. What is shown here is actually a metal cored wire. It's similar to a gas-shielded (FCAW-G), in that it has "flux" powder inside and gas-shielding. But, it does not produce a slag on the weld.
In my experience,dual shield is a great product. It yields great strength and isn't fussy about minor rust or mill scale. My Millermatic doesn't like it. Even with knurled drive rollers. I've used it in other machines with great results.
Much less spatter and much less fumes with pure argon! The weld looks much better although the puddle did look cooler with the lower speed. Thanks so much for sharing!
I think the terminology got mixed up a little bit in this video. A reference to a 70T wire was made when in essence you are running a 70C wire, Big difference between flux core and metal core wires.
I weld with metal core all day every day on 75/25 .035 I run around 26.5 ws 710 or 100% argon 26.5 ws 650 and make them flawless like they was robot welded. Metal core is wierd at first to get used to but man I love it flows so good and weld fast fast
Bob love your videos, we just did a project on a Marine exhaust system that required 70.6 wire .035 with a gas 92/8 and in position with a load of obstacles in our way witch made the Welding a total bitch but we got it done but the gas mix I found gave positive weld and almost not splatter, just something you may want to try sometime on the mig straight wire we are trying it out now with the left over gas mix for our everyday steel projects. Thx for your video JM/ Doll Marine
Run the Lincoln NR 232 flux inner shield . 0.72 that is the standard for structural steel welding in California . It meets all the FEMA standards for moment connection etc.. Although there are other wires for structural steel this wire would be concerned the hardest and most challenging to run because it is not very forgiving like other welding wire . Bottom line , guys whom are learning will need to practice this quite a bit to perfect the process. Once its perfected the money starts pouring in your pocket; especially, in the structural steel welding arena .
bob the spray transfer you talk about is running reverse polaity right or wrong i like the weld bead the 100% argon produced that was the cleanest weld ive seen i use to work in a fab shop we did stainless steel for jetstream ovens and it was straight argon thnxs
I must say that 100% argon and the 70T-1 dual shield wire makes the best looking mig weld I've ever seen on mild steel but it must be an expensive way to weld mild steel with mig?
I think it's crazy anybody would ding your welds. I'd like to see theirs. In the world I live in, a good weld is one with good penetration so it won't break that looks good. From everything I've seen here, your tops!
After watching the video a couple times, the way it's presented, it's confusing. The title of the vid is metal core wire. I assume that means solid wire. But @9:29, he clearly says "again, tubular dual shield wire" ...
yeah...the 1st dualshield I ever ran was in 1985....100% C02 and 1/16" wire....ran 40-50#'s in a 10 hour day....2"-4" plate all the time....sometimes 6"....lots of beads in there.....
The place was a sub-contractor for Aero-Jet...I made mandrels for the machinists to turn on lathe/s for nosecone fiber-winding....I seem to recall the wire was in 60# rolls?...30 to a pallet... we'd get a full pallet about every couple weeks.... I often ran a bead for 20-30 minutes without stopping....lots of stuff was on a rotator....
Doug Ankrum that sounds to a T how things are running here. we don't do any maintenance type work though. all fab. the project I'm working on now is for 1144 fifteenth st in Denver, co. that's our bread and butter
what filter are you using on your camera? I really like the way the arc is defined, realizing that it is zoomed in. It looks to me like a magenta fixed shade lens. Is that correct?
Hey Bob Moffatt. what brand wire and spool size are you using. I am having a really hard time finding spools of dual shield wire small enough to fit in my esab rebel and Lincoln 210mp.
I have a 300 cf argon tank. I wanted to set up another tank for co2. My desire is to use the 2 gases to make argon 90/ 20 co2. I have 2 regulators. Any suggestions of how to set it up. I saw ebay has dual shielding gas regulators. Thanks
I did a quick search after this video about TIG welding with 100% argon and could not find anything. Is that anything that is done if not why not? Can it be done? I would like to see that.
Almost all TIG welding is done with 100% argon. Chances are if you watched any TIG video on UA-cam it's being welded with argon (unless otherwise stated).
Not a tubular wire, t wire would have flux in it and would have to drag it that’s cored wire aka metal core u can push or pull and it’s a flat and horizontal wire but if u have a pulse machine u can run it uphill at least up here in Canada that’s how we classify it
I had an experience w my last job. We ran just regular 0.35 mig wire 100% argon on 10g carbon steel w a Miller 252 and well, most everyone there would jack the machine up! I mean as high as it would go. I think 29 volts and 700 ipm. I never got that but I got used to it. Can you explain that one to me?
I've asked the same thing on a few other videos. Never seem to get it. I'm interested in seeing the weld nugget difference between the C25 and pure argon.
+Defnotdemas doesn't look like it to me. Watch the video again, there are at least two parts in the video where Bob stopped the demo and began talking immediately. I didn't see any slag and I didn't see him clean it off. Not like any dual shield I've ever seen.
It would be nice if you could show the purpose of that table . For example, set your strong arm bars / clamps showing a strong back hold on a weld piece application.
It's actually not a Strong Hand Tools Table, it's called a FAB block. They are purchased as a kit and you weld it up yourself. VERY AFFORDABLE and we couldn't recommend them enough. That being said, we do have some fixturing for them that we use on occasion.
At 3 minutes and 30 seconds she says this is a 70 series tubular wire a flux cored wire correct me if I'm wrong if that's the case this is what most people would call a dual Shield
Co2 is an active gas,argon is an inert gas. each gas will affect arc voltage,arc voltage will affect heat imput , heat imput will affect deposition rate and fussion.
Wait I’m so confused, I just watched their other video that said er70s-6 runs like shit with 100% argon. So can I use 100% argon for MiG or no? I can’t tell if he’s using flux or standard feed wire
Great presentation, you are getting relaxed and comfortable being in front of the camera, it shows, your allowing the information to just flow out and be absorbed by all easily, Great Job!!
I never would have thought to use straight argon on a flux core wire but wow what a difference that made good stuff man

Glad to see you know . Some of the clowns on here after your comment don't get it .
@@scottfunderburk2071 powdered metal actually not technically a flux as it is all part of the final weld deposit
In my experience,dual shield is a great product. It yields great strength and isn't fussy about minor rust or mill scale. My Millermatic doesn't like it. Even with knurled drive rollers. I've used it in other machines with great results.
Definitely trying this on Monday. Ive been avoiding this wire because my shop wont buy 90/10 for spray and I hate chipping spatter off.
Much less spatter and much less fumes with pure argon! The weld looks much better although the puddle did look cooler with the lower speed. Thanks so much for sharing!
Mig welding with argon is a colder gas.
So not much splatter but the weld puddle isn't as hot, have to keep that in mind.
Dual shield wire is like that good dog you had, always seems to know how to behave it's self without much effort on your part
I think the terminology got mixed up a little bit in this video. A reference to a 70T wire was made when in essence you are running a 70C wire, Big difference between flux core and metal core wires.
Thats my boy.
I weld with metal core all day every day on 75/25 .035 I run around 26.5 ws 710 or 100% argon 26.5 ws 650 and make them flawless like they was robot welded. Metal core is wierd at first to get used to but man I love it flows so good and weld fast fast
At my work we run metal core in spray all day long !, 75/25 gas run hot hot hot 🥵 awesome video bob
great looking bead with the 100% argon!!! but one hell of an expensive way to making it look that good!!!!
More welding videos using everlast welders please. I really would like to know what settings I should use for different cases.
well that gives me something to think about, i have a Lincoln 210power mig. been using the flux wire because I don't have the gas for the solid.
I welded some regular old flux core wire off 100% Argan and I got to tell you it was a very weird experience very unusual result I got from it
I wonder what would happen welding 18 ga sheet metal, as far as warpage, using argon? I've enjoyed your videos. Thanks
I'm a big fan of your videos, lots of good information.
Bob if possible could you please run a dual sheild flux core using 100% CO2. Most of them call for a 75/25 mix.
Why is there no slag? I've never ran a dual shield that didn't have a slag of some sort. Looks like hard wire to me for
nicholas newcomb he was running metal core not flux core
I'm getting to play around with some .052 MetalCore at work in our weld class. Running it with 100% Argon. Seems so far to be a Picky wire.
He is a heavy metal rock star!!!
Bob, can you do an experiment with self shielded wire and argon gas (or C25) together please?
Lincoln company explains why you shouldn't do this!
Bob love your videos, we just did a project on a Marine exhaust system that required 70.6 wire .035 with a gas 92/8 and in position with a load of obstacles in our way witch made the Welding a total bitch but we got it done but the gas mix I found gave positive weld and almost not splatter, just something you may want to try sometime on the mig straight wire we are trying it out now with the left over gas mix for our everyday steel projects. Thx for your video JM/ Doll Marine
I know with flux core you have to switch electrodes. Did you keep DCEN for this video. Maybe I missed it in your introduction.
Hi. Great job. Will run a .035 on 100% argon so some of my classmates can learn what to expect. Aluminum
What wire do i use for 100 argon for stainless steel? Anyone know of a brand or wire type
Run the Lincoln NR 232 flux inner shield . 0.72 that is the standard for structural steel welding in California . It meets all the FEMA standards for moment connection etc..

yes I like the first weld 550 ipm and 25 amp looks clean even second one looks uneven like did not tie in pretty good i nthe bottom
A lot of welds sometimes do not come out pretty looking you have to experiment with gas and voltage and wire speed
I must say that 100% argon and the 70T-1 dual shield wire makes the best looking mig weld I've ever seen on mild steel
but it must be an expensive way to weld mild steel with mig?
I think it's crazy anybody would ding your welds. I'd like to see theirs. In the world I live in, a good weld is one with good penetration so it won't break that looks good. From everything I've seen here, your tops!
Only thing i can see thats a tiny bit goofy is the gas mixture the best is 90/10 im a union ironworker and this is what my shop calls for
Great instructional videos, thanks.
I may have missed something here but, if this is fluxcore wire where is the slag? Does it go up in smoke?
have not heard any fluxcore as far as I know argon and c25 r use when there is no flux inb the wire but Im no an expert
This process is called Dual Shield Fluxed Core, Its a Tubular Wire with Flux plus the Shielding gas (Ar or C25). thats why there is so little fume.
Jose Arrue this is not dual shield. there's no slag so no flux
After watching the video a couple times, the way it's presented, it's confusing. The title of the vid is metal core wire. I assume that means solid wire. But @9:29, he clearly says "again, tubular dual shield wire" ...
You´re right
See pure argon is good for certain applications, try running a mix of argon and helium for penetration
Does the polarity need to be changed with the flux core and argon
Awesome bob your always polite and humble stay blessed always
What’s the difference from dual shielded and Mig welding?
Hi from Greece nice tips good work
,You already have a Mig Monday, and you should do a Tig Tuesday or Thursday, and Stick Saturday or Sunday.
What's the part number on that wire?
I want to give straight CO2 a try with my everlast welder. I understand it has the potential to cut my costs.
Alex Rodríguez it’s going to have more slag
And a crap ton of spatter
Btw I use weaves just for that issue with your bead not blending
Used to do code structural with flux core . Used to use 95- 5 gas. Don't remember what type of flux core wire. It was back in like 2003
Ran like a spray arc
Nice one Bob
Question would the 71T be close to same outcome?
id really like to see you run 70s 1/16" fcaw-g 100% co2. I run it all day everyday and I wanna see a professional lay some down.
yeah...the 1st dualshield I ever ran was in 1985....100% C02 and 1/16" wire....ran 40-50#'s in a 10 hour day....2"-4" plate all the time....sometimes 6"....lots of beads in there.....
Doug Ankrum yes, that is totally correct. I've even pushed a little over 50lbs a couple days. super hot and heavy
The place was a sub-contractor for Aero-Jet...I made mandrels for the machinists to turn on lathe/s for nosecone fiber-winding....I seem to recall the wire was in 60# rolls?...30 to a pallet... we'd get a full pallet about every couple weeks.... I often ran a bead for 20-30 minutes without stopping....lots of stuff was on a rotator....
Doug Ankrum that sounds to a T how things are running here. we don't do any maintenance type work though. all fab. the project I'm working on now is for 1144 fifteenth st in Denver, co. that's our bread and butter
You are a professional
lol. I weld with lincoln 71m Tri-mark 770 daily ... The question is where is the slag?
He said 7000 series, not 7100. It's metalcore tubular wire, not fluxcore.
5, 6 and 700 in/min!? must have the new 235
Thanks for the vids!
What is the line down the middle of the welds when you changed to pure argon gas.,
how you can record your welds without any distortion on the camera and which camera you use thanks and I love your channel
Put welder visor in front of camera
Love your video really well explain good job !
what filter are you using on your camera? I really like the way the arc is defined, realizing that it is zoomed in. It looks to me like a magenta fixed shade lens. Is that correct?
Phillips Alloweld with Magenta drop in.
Thanks, again - great video.
I really want to come there and be taughr by you someday.
Where do I get the 70 T dual shield wire? Or is there another name for it?
great video very informative
Hey Bob Moffatt. what brand wire and spool size are you using. I am having a really hard time finding spools of dual shield wire small enough to fit in my esab rebel and Lincoln 210mp.
Hope you are doing OK Bob.
I repair car parts my job does 100% argon with mig silicone bronze and 90% argon and 10% CO2 with steel mig . 45 wire size for each one
I have a 300 cf argon tank. I wanted to set up another tank for co2. My desire is to use the 2 gases to make argon 90/ 20 co2. I have 2 regulators. Any suggestions of how to set it up. I saw ebay has dual shielding gas regulators. Thanks
Can't tell if this is a push or slight pull ???
Another great video, learned a lot. Is there a penetration difference in C25 and Argon?
Thanks
Charlie
argon looks cleaner but I remember seing other video when the cugt looked at the weld nugget and penetration is less with argon
I did a quick search after this video about TIG welding with 100% argon and could not find anything. Is that anything that is done if not why not? Can it be done? I would like to see that.
Almost all TIG welding is done with 100% argon. Chances are if you watched any TIG video on UA-cam it's being welded with argon (unless otherwise stated).
Well don't I feel ignorant haha. Thanks for the reply and info.
That's what we're here for. Thanks for watching!
We have to run our metal core with 8C is in their qualification.
Not a tubular wire, t wire would have flux in it and would have to drag it that’s cored wire aka metal core u can push or pull and it’s a flat and horizontal wire but if u have a pulse machine u can run it uphill at least up here in Canada that’s how we classify it
HI
What is the numbering for the wire Bob is using and is there an all position version?
C.O.P.S
NZ
Great vid a lot of structuralShops are going to this ours is one
I had an experience w my last job. We ran just regular 0.35 mig wire 100% argon on 10g carbon steel w a Miller 252 and well, most everyone there would jack the machine up! I mean as high as it would go. I think 29 volts and 700 ipm. I never got that but I got used to it. Can you explain that one to me?
Production. Weld hot and fast.
Would have been nice to see a cut and polish to see the cross section.
I've asked the same thing on a few other videos. Never seem to get it. I'm interested in seeing the weld nugget difference between the C25 and pure argon.
Great ideas guys. Hang in there and we will start doing it.
What brand of wire is it.
Peter Babb Hobart wire
Thank you.
That bead should be smooth like glass.
weld.com what wire are you using. I thought dual shield had slag on it. I am interested in trying this
This is a metal core wire.
Use 98/2 with metalcore wire and ot will run clean soft and hot
It
good info, thanks
I would like to see a bead laid down with the wire just pushed down the weld without the mig like tig look.
So it's dual shield but doesn't leave slag over the finished weld??
+Defnotdemas doesn't look like it to me. Watch the video again, there are at least two parts in the video where Bob stopped the demo and began talking immediately. I didn't see any slag and I didn't see him clean it off. Not like any dual shield I've ever seen.
its a mistake on his part. hes running metalcore wire, it doesnt leave slag
70T is metal core. 71T/M is flux. He made a small booboo. Oh well. Man welds like a champ.
E70C-6 is Metal Core Wire.
What is the purpose for that work bench with all the holes?
fixturing
It would be nice if you could show the purpose of that table . For example, set your strong arm bars / clamps showing a strong back hold on a weld piece application.
It's actually not a Strong Hand Tools Table, it's called a FAB block. They are purchased as a kit and you weld it up yourself. VERY AFFORDABLE and we couldn't recommend them enough. That being said, we do have some fixturing for them that we use on occasion.
So why use C25 at all if Argon gives better results?
Hyss The price of 100% argon is a lot more $$ than C-25 75/25 mix...
Don’t believe that was flux core!?
Nice vid, thx!
this is metalcore wire not dual shield
At 3 minutes and 30 seconds she says this is a 70 series tubular wire a flux cored wire correct me if I'm wrong if that's the case this is what most people would call a dual Shield
I have a question I was told to run metal core wire on pulse is that not true
No point unless you are welding vertical.
do you think pure argon can be use with a er70s-6 wire?
Mr. green I want to see that video
Mr. green watch the whole video he tells you what happens with solid wire on pure argon it is a no go
Only if I have to. It's not good from undercut next to toe of weld. Pool is unstable and does not wet into parent metal.
Bob Moffatt thanks bob! i dont do steel. everything i do is aluminium, but it's not to say i wont do steel in the future.
Has anyone ever tried mig welding with the inner wire of a coaxial cable? That is copper-plated steel.
Damn it if bob mofett didn't do this video i wouldn't have watched
The pure argon turned it into true spray
Co2 is an active gas,argon is an inert gas. each gas will affect arc voltage,arc voltage will affect heat imput , heat imput will affect deposition rate and fussion.
Of course you can weld it with 100% but your not allowed to your WPS ( Welding Procedure Specification)
Great!!!
could you do wire give aways ?
Wait I’m so confused, I just watched their other video that said er70s-6 runs like shit with 100% argon.
So can I use 100% argon for MiG or no? I can’t tell if he’s using flux or standard feed wire
He is welding with metalcore wire different than flux core
@10:05. Your wire was fine for the gas being used. That bead was nice
Do you teach welding? lmao. Teach a college course , then come back when you have knowledge to correct someone.
that's not dual shield wire.
yea most likely metal core
if you are using flux core that is why you have a lot of smoke
We are not allowed to whip either.
flux core you do not need argon or co25 gas
gamo98 why do you think it's called dual shield if you don't need gas?
Who the hell doesnt clean the scale off surfaces? Do people really work like that in the US?
A lot of times you really don’t need to, especially with flux core, stick, and dual shielded welding, it’s a waste of time.
At like 3 minutes and 30 seconds he says this is a tubular wire a flux cored wire
no way that's flux core. it's metal core
he even says 70C at one point
Flux core either welds with gas or strictly inner-shield. Hard face welding wire is a good example of that
Lou yes we run stellite 6 metal core at work
Too much spatter. Unacceptable at my factory.
And don't whip it.
Fabcore wire. You are running to much wire.
